Tech Note for Nerds

From The Frame Grab Tutorial:

Apple's QuickTime help describes data rate:

When you export a QuickTime movie, you can set the data rate for a few compressors, such as Cinepak and H.263. The data rate is the amount of data that is played per second, usually measured in kilobytes or megabytes per second. The data rate of a movie is affected by other compression options you set.

You may want to set a data rate based on the way your movie will be viewed. For example, if you want a movie to play from double-speed CD-ROM drives, you need to limit the data rate to a maximum of about 250 kilobytes per second.
